This paper deals with the modeling of punching shear failure in reinforced concrete slabs using nonlinear finite element analysis. The 3D finite element analyses (FEA) were performed with the appropriate modeling of element size and mesh, and the constitutive modeling of concrete. The FE numerical models are validated by comparing with the experimental results obtained from tested specimens and...

EXECUTIVE SUMMARY This report presents the results of a pilot study to apply externally bonded Carbon Fiber Reinforced Polymer (CFRP) sheets to strengthen a simple span reinforced concrete solid slab bridg...

Ferritin synthesis is controlled at the translational level in response to cellular iron status. A component of this regulatory system is the ferritin repressor protein (FRP) which binds to the iron-responsive element (IRE) located at the 5' end of all known ferritin mRNAs, thus inhibiting its translation. Antibodies against purified FRP were raised in mouse and used to isolate an FRP cDNA from...

Vibrio harveyi NADPH:FMN oxidoreductase P (FRP(Vh)) is a homodimeric enzyme having a bound FMN per enzyme monomer. The bound FMN functions as a cofactor of FRP(Vh) in transferring reducing equivalents from NADPH to a flavin substrate in the absence of V. harveyi luciferase but as a substrate for FRP(Vh) in the luciferase-coupled bioluminescent reaction. As part of an integral plan to elucidate ...

Advances in the fields of polymers and composites have resulted in a major development of high strength fibre reinforced polymers (FRP). These materials offer great potential for cost-effective retrofitting of concrete structures. In response to the growing need for concrete repair and rehabilitation, an experimental program was conducted at the University of Manitoba in Winnipeg, Manitoba, Can...

Fiber Reinforced Polymer (FRP) bridge systems are gaining wide acceptance among bridge engineers. At the same time, FRP bridge systems are relatively expensive when compared to traditional reinforced concrete bridge systems. In this study, the concept of the hybrid FRP-concrete structural systems is applied to a bridge superstructure. The hybrid FRP-concrete superstructure system is intended to...

Fiber-reinforced plastics (FRP) production in many cases involves expensive molds, which especially hinders cost-effective of small series and prototypes. In metal parts production, incremental sheet forming (ISF) is an established process for creating individual through a flexible die-less process. Establishing similar FRP desirable but challenging, as deformation mechanisms endless differ sig...

Vibrio harveyi luciferase and flavin reductase FRP are, together, a two-component monooxygenase couple. The reduced flavin mononucleotide (FMNH2) generated by FRP must be supplied, through either free diffusion or direct transfer, to luciferase as a substrate. In contrast, single-component bifunctional monooxygenases each contains a bound flavin cofactor and does not require any flavin addition...
